Specification of Letters Patent.

Patented June 22, 1%15.

Application filed April 19, 1915. Serial No. 22,458.

To all whom it may concern Be it known that we, NATHAN GENn'rHo TULLERand ANDREW MATlI-IE\V RASMUSSEN, citizens of the United States, residingat Beloit, in the county of Rock and State of Wisconsin, have inventedcertain new and useful Improvements in Ice-Skates, of which thefollowing is a specification, reference be ing had to the accompanyingdrawings.

Our present invention relates to new and useful improvements in iceskates and as its principal object aims to provide a skate in which thesole plate is yieldably supported. on the runner by a novel form ofshock absorbing support.

Another object is to construct a shock absorbing supporting member,which is designed with such regard to proportion, number and arrangementof parts, that it may be cheaply manufactured, will be durable andefficient in service and may be readily applied to or removed from theskate, without requiring any extended changes or alterations in theconstruction thereof.

A. further and more specific object of the invention is to provide asupport which is particularly adapted for application to the rear end ofthe sole plate and consists essentially of a pair of telescopingmembers, between which is interposed a helical spring adapted to absorb,to a considerable extent, all the shock and impact ordinarilytransmitted from the runner to the sole plate, as a result of contact ofthe runner with rough ice or when the skater is jumping, hurdling orperforming some similar feat.

The above, and other incidental objects of a similar nature, which willbe hereinafter more specifically treated are accomplished by such meansas are illustrated in the accompanying drawings, described in thefollowing specification, and then more particularly pointed out in theclaim which is appended hereto and forms part of this application.

With reference to the drawings, wherein there has been illustrated thepreferred embodiment of this invention, as it is reduced to practice,and throughout the several views of which similar reference numeralsdesignate corresponding parts.

Figure l is a side elevation of the skate; Fig. 2 is a vertical sectiontaken through the shock absorbing member; Fig. 3 is a top plan view ofthe sleeve of the supporting member; and Fig. lis a detail perspectiveview of the stud of the supporting member.

As disclosed particularly in Fig. l of the accompanying drawings, thesupporting member designated, as an entirety by the letter A isespecially designed for application to the sole plate B of the skate atthe rear termlnal thereof. It will, of course, be understood, however,that the member A may be employed in connection with the tip of the soleplate or as a supporting member for the heel plate, without departing inany way from the spirit of the invention.

The supporting member A. consists essentially in three elements, atubular sleeve 10, a stud or stem 11 and a helical spring 12 which isdisposed within the sleeve and normally tends to project the stud fromthe sleeve. 6

The sleeve 10 is, as stated, preferably tubular in shape, although itmay be polygonal, if so desired. The upper end of the sleeve is closedby a circular head plate 13 which is of greater diameter than the sleeveand is provided adjacent its perimeter with a plurality of threadedbores 14. Fastening screws indicated at 15, are passed through receivingapertures 16 formed in the sole plate B adjacent the rear end thereoffor threaded engagement in the bores of the head plate, for the obviouspurpose of rigidly attaching the sleeve to the sole plate. The sleeve 10is of a length less than the distance normally included between the soleplate and the upper edge of the runner 17 when the sole plate is inparallel relation thereto. The stud or stem 11 is bifurcated at itslower terminal, as indicated at 18 to produce the parallel lugs 19. Asshown in Fig. 2 the lugs are engaged against opposite faces of therunner when the stem is applied thereto. The upper end of the stem iscored out to form a socket 20, in which the lower end of the spring 12is seated. The upper end of the spring 12, of course, bears against thehead plate. The spring, when not under compression, tends to hold thestud partly projected from the sleeve as in Fig. 2.

From the foregoing description, it will now be seen that the supportingmember A serves as a shock absorbing element which will take up anyimpact or jars to which the runner of the skate is subjected. It willalso be seen that inasmuch as the supporting member A is extensible, thesole plate is yieldably supported at its rear end so that it may readilyconform to the surface of the shoe sole of the skater.

In reduction to practice, it has been found that the form of thisinvention illustrated in the drawings and referred to in the abovedescription as the preferred embodiment, is the most eflicient andpractical; yet realizing that the conditions concurrent With theadoption of this device will necessarily vary, it is desirable toemphasize the fact that variousminor changes in the details ofconstruction, proportion and arrangement of parts may be resortedto,-When required, without sacrificing any of the advantages of thisinvention, as'defined by the appended claim. I

What is claimed is The combination With a skate, of a shock absorbingsupporting member for the sole plate thereof, said supporting memberincluding a stud having its lower terminal bifurcated to receive theskate runner and having a socket formed in its upper terminal, a sleeveslidably receiving the stud, a head plate formed on the sleeve,fastening devices detachably securing the head plate to the plate.

In testimony whereof We hereunto al'lix our signatures in the presenceof two Witnesses.
